The Boundless Sea (Region Sum Lines)
(Eingestellt am 6. März 2026, 14:45 Uhr von Kutsumi Hane)
Rules:
Normal Sudoku rules apply, requiring that each row, column, and 3×3 box contains the digits 1-9 exactly once. Additionally:
-
·Toroidal Grid:
The grid wraps around both horizontally and vertically.
·Main Diagonal: Every 9×9 Sudoku grid in the plane has 1–9 on its main diagonal.
·Region Sum Lines: The blue line has equal sums in each region it passes through.
·Separator Dots: Digits between consecutive yellow dots along the blue line are all different.
·Anti-Knight: Cells a knight's move apart cannot contain the same digit.
·Inequality: Inequality signs between two cells point toward the smaller digit.
Here you can solve the puzzle online:
The difficulty is probably 4 stars. I wish you joyful solving!
Hint:
| · | Start by determining the sum of each region sum line. |
| · | During the solve, it may be necessary to use letters in place of digits for most of the deduction. |
| · | Familiarity with the Magic Square may be essential for solving the puzzle. |
Lösungscode: Digits on the anti-diagonal (from top to bottom)

very nice puzzle, enjoyed it a lot..
but since it's heavily symmetric I do not think it's a 4*
(2*; maybe 3*, since the wrap around is quite a bit trickier to scan at first but once you got used to it it's a smooth ride)
Really enjoyed it
